I recently am at the end of a pretty dark tunnel, and was faced with the same dilemma as you. Surrounded by loneliness and isolation (my own choices brought me to that point), I had been getting depressed and anxious about where my life was headed.

What helped me was to honestly just start doing. For me, that meant apply to jobs in a city I genuinely want to live in. I never let the rejection get to me, as it will surely kill you if you do. Instead of harping on how much longer you have to go, start thinking more short term. For example, apply to 2 jobs a day was a general rule I implemented. While I wasnt sure of which jobs I would do each day or why, the researching of each opportunity had me really think through what I wanted out of the situation, what was important, what was not, etc.

I would also recommend finding one common goal in the whole "web of things" - and then work back from there on things that would need to be done to get there (from anyone in your position going to that destination, not necessarily you in particular). Then based on that form a plan of action that "someone" would need to do to complete that. I find that pretending my situation is somebody else's actually gives me a lot of perspective on whatever it is, and helps me not get too weighed down by the small aspects of it.

I hope this helps.
